We had a wonderful eight-night stay at the duplex. (The person who wrote the one-star review must be a hypochondriac or perhaps a grifter. There are no bed bugs, and to suggest that the property was "uninhabitable" is patently absurd.) My wife and I and our two young kids had one side; in-laws were in the other. We loved that the property was at a narrow part of the island so there was a wild, windy beach on one side and a sheltered, safe bay on the other. For the kids, the huge intertidal zone was a great place to wade, wander, and splash around. I did snorkel a bit on the windward side but for most of the (very windy) week it was too rough to try.
It was great having two golf carts at our disposal. A few of us went up to the small harbor at the northern end of the island almost every day to go spearfishing out in the channel, and we usually rode into Black Point "town" a few times a day to get groceries, buy conch salad from the guys at the dock, or just putter around. We also took the carts down to Plain Beach, which is pretty much at the end of the road. We had one flat tire which Marko replaced very quickly. Marko also took us out on a boat to see the swimming pigs and the iguanas, the Thunderball grotto, lunch at Staniel Cay Yacht Club, and some good spearfishing spots. He and just about everyone else we met on the island were friendly and helpful, without being too omnipresent.
Complaints? Nothing major. The windy weather did have some screens and doors rattling a bit, and I think some of the latches could stand to be replaced. All minor stuff. A hammock or two on the gazebo would be awfully nice.
To-do: Buffet at Lorraine's (great food, great price), quiet dinner at Deshamon's, happy hour at Scorpio. Definitely do a day on a boat to see the nearby sites. If you do any spearfishing, go with a boat or set up a small floating tank/bucket contraption to hold your speared fish. The first day we went out, I had several speared fish on a float line (as I'd done many times in the South Pacific, without incident) and when we were almost back to the dock I let my guard down for a few moments and when I turned back to look at the fish I saw a Caribbean reef shark about two meters away. I watched helplessly as it grabbed the fish and yanked the whole line right out of my dive partner's hand. We ended up finding an empty gas can on the windward beach, which we converted to a floating fish hold. No further run-ins with sharks after that.
